Do more at once with the new Compact Overlay window: Ever want to continue watching a movie while switching app to check your email? Or keep an eye on your video chat even as youâre browsing the web? We do all the time! Some tasks donât require the userâs full attention but is perfect to leave at the corner of the screen so weâre introducing a new compact overlay mode for UWA app developers. When an app window enters compact overlay mode itâll be shown above other windows so it wonât get blocked. The best part is that compact overlay windows work just like normal windows in all other ways so app developers can tailor the experience with what they already know. Updates to the Movies & TV app and Skype Preview app will take advantage of compact overlay windows in the near future!Introducing Dynamic Lock: Dynamic Lock automatically locks your Windows 10 PC when youâre not around based the proximity of a Bluetooth-paired phone. If your Bluetooth-paired phone is not found near your PC, Windows turns off the screen and locks the PC after 30 seconds. To enable Dynamic Lock, make sure your phone is paired to your PC via Bluetooth and go to Settings > Accounts > Sign-in options and toggle Dynamic lock to âonâ.NOTE: See known issues below regarding a bug preventing PCs on this build from successfully pairing devices via Bluetooth. New Share icon: Weâre introducing a new share icon. Apps that used the âshareâ font glyph in Segoe MDL2 assets should get the change automatically. You can read more about the change here.Windows Game Bar improved full-screen support: We got a ton of feedback on Game Bar and we are continually adding more titles with this support. In this build, weâve added support for 52 additional games in full-screen mode with Windows game bar. As always, just hit WIN + G to invoke Game Bar to capture a recording or screenshot.

Tip: You can control this feature through the Windows Game bar settings. In the settings dialog, look for the âShow Game bar when I play full-screen gamesâ checkbox. See Major Nelsonâs post on Game bar for more info on how to adjust settings for best game performance.

Other changes, improvements, and fixes for PC

We fixed the issue causing Tencent apps and games to crash or work incorrectly.

Weâve updated OOBE so that if thereâs no detected audio output device, for example with VMs, it now skips Cortanaâs introduction.

[GAMING] We fixed the issue causing popular games may experience crashes or black screens when trying to load due to a platform issue.

[GAMING] We fixed the issue where Game Mode is enabled system wide by default, however, the ON/OFF toggle in Settings will incorrectly show it as being OFF until the user manually toggles the Setting to ON which will cause it to update and accurately display the status of Game Mode system wide.

We fixed an issue where the night light quick action was unexpectedly disabled in the last Insider flight.

We fixed an issue resulting in audio going quiet each time the Start menu is opened after a SpeechRuntime.exe crash.

Dragging apps from the all apps list to pin on Startâs tile grid will now work. We also fixed an issue on recent builds where some tiles might unexpectedly appear blank and with a name starting with âP~âŚâ after upgrading.

We fixed an issue where Win + Shift + S wouldnât work to capture a region of the screen if the Snipping Tool was already running. We also fixed an issue where taking a snip with the Snipping Tool would fail on 4k monitors when 60-80% was selected.

We fixed an issue resulting in âFnâ+âPause/Breakâ key not working to pause the checking progress when running chkdsk.

We fixed an issue where resizing windows with a pen would be unexpectedly slow. We also fixed an issue where resizing a window across monitors with different DPIs could be unpredictable.

We fixed an issue where the Windows Ink highlight preview wouldnât be visible in Web Notes when Microsoft Edge was using dark theme.

We fixed an issue where a number of files with the name GLOB(0xXXXXXX) could be unexpectedly found in the system root directory after upgrading.

We fixed an issue where you couldnât rename disk volumes via File Explorer in recent flights.

We fixed an issue where rapidly tapping a button to bring up the new Share experience, for example in Microsoft Edge, could result in the Share UI not coming up again until the device had been rebooted.

We fixed an issue resulting the lists of thumbnails in Photos and Groove Music visibly shifting up when the app resumed.

We fixed an issue where the Themes Settings page would blink when a theme was deleted.

Weâve updated the help string on each page of Settings to be a bit more succinct.

We fixed an issue resulting in not being able to type Ä on the Polish keyboard into the Settings search box.

We fixed an issue where Cortana Background Task Host might have ended up using an unexpectedly large amount of CPU in recent flights. We also shorted the two factor authentication notification from Cortana so that it wonât be truncated.

We fixed an issue where the UI to input credentials wouldnât have keyboard focus after initiating a remote connection to another PC.

The icons should now be shown as expected instead of squares under Settings > Gaming.

Well, this is a preview right? So here are the known issues :

[UPDATED] IMPORTANT: You may see âInitializingâŚâ when attempting to download this build and the download progress indicator shown when downloading this build may seem broken under Settings > Update & security > Windows Update. It may look like youâre getting stuck at 0% or at other percentages. Ignore the indicator and be patient. The build should download fine, and the installation should kick off. See this forum post for more details.

While we fixed the primary bug causing this issue, some Windows Insiders may still hit nonstop exceptions in the Spectrum.exe service causing their PC to lose audio, disk I/O usage to become very high, and apps like Microsoft Edge to become unresponsive when doing certain actions such as opening Settings. As a workaround to get out of this state, STOP the Spectrum.exe service and delete C:ProgramDataMicrosoftSpectrumPersistedSpatialAnchors and reboot. For more details, see this forum post.

Going to Settings > Devices will crash the Settings app. You will be unable to pair a Bluetooth device. Bluetooth quick actions from Action Center also does not work.

You will not be able to launch the Connect UX via Action Center, Win + K, or Settings (it will crash upon launch). This will impact wireless projection scenarios.

[GAMING] Some popular games might minimize to the taskbar when launched. You can click on the game on the taskbar to get the game back.

[GAMING] Certain hardware configurations may cause the broadcast live review window in the Game bar to flash Green while you are Broadcasting. This does not affect the quality of your broadcast and is only visible to the Broadcaster.

Under Settings > Update & security > Windows Update you might see the text âSome Settings are managed by your organizationâ even though your PC isnât being managed by an organization. This is a bug caused by an updated flight configuration setting for Insider Preview builds and does not mean your PC is being managed by anyone.

On some PCs, audio stops working sporadically with âdevice in useâ errorâ. We are investigating. Restarting the audio service may fix things for a bit.

The Action Center may sometimes appear blank and transparent without color. If you encounter this, try moving the taskbar to a different location on screen.

The icon for Windows Insider Program under Settings > Update & security is shown as a square.

This is all for the PC Build . Stay tuned to MSLeaks to stay updated to everything related to Microsoft!
